Saharashina Yumiko

Upon noticing the reduced amount of customers you decided to hop back to the break room and let the rest of the staff take care of it. As you walked through the short and obscure hallway that led to your destination, you were fantasizing on eating your sandwich that you carefully prepared in the morning.
When opening the door your dream got shattered into pieces as you saw Yumiko lying on the table at the center like a dead corpse, next to her was your lunch box with only a few crumbles remaining.
"..." She was groaning in satisfaction as she kept her eyelids shut and enjoyed her not so well-deserved break.
Before you could say anything to her, she spoke up:
"The others don't need me..." Her usual paused and tired tone muffled as her face faced down the table. "Wake me up at the end of the shift..." Yumiko had the balls to sleep in front of her boss (you). And while she was the best cook at the café, she also was a serious slacker.
